i965: Fix textureGrad with cube samplers

We can't use sampler messages with gradient information (like
sample_g or sample_d) to deal with this scenario because according
to the PRM:

"The r coordinate and its gradients are required only for surface
types that use the third coordinate. Usage of this message type on
cube surfaces assumes that the u, v, and gradients have already been
transformed onto the appropriate face, but still in [-1,+1] range.
The r coordinate contains the faceid, and the r gradients are ignored
by hardware."

Instead, we should lower this to compute the LOD manually based on the
gradients and use a different sample message that takes the computed
LOD instead of the gradients. This is already being done in
brw_lower_texture_gradients.cpp, but it is restricted to shadow
samplers only, although there is a comment stating that we should
probably do this also for samplerCube and samplerCubeArray.

Because of this, both dEQP and Piglit test cases for textureGrad with
cube maps currently fail.

This patch does two things:
1) Activates the texturegrad lowering pass for all cube samplers.
2) Corrects the computation of the LOD value for cube samplers.

I had to do 2) because for cube maps the calculations implemented
in the lowering pass always compute a value of rho that is twice
the value we want (so we get a LOD value one unit larger than we
want). This only happens for cube map samplers (all kinds). I am
not sure about why we need to do this, but I suspect that it is
related to the fact that cube map coordinates, when transported
to a specific face in the cube, are in the range [-1, 1] instead of
[0, 1] so we probably need to divide the derivatives by 2 when
we compute the LOD. Doing that would produce the same result as
dividing the final rho computation by 2 (or removing a unit
from the computed LOD, which is what we are doing here).

Neil Roberts [Thu, 28 May 2015 18:35:44 +0000 (19:35 +0100)]
i965/vec4: Fix the source register for indexed samplers

Previously when setting up the sample instruction for an indirect
sampler the vec4 backend was directly passing the pseudo opcode's
src0. However vec4_visitor::visit(ir_texture *) doesn't set the
texture operation's src0 -- it's left as BAD_FILE, which when
translated into a brw_reg gives the null register. In brw_SAMPLE,
gen6_resolve_implied_move() inserts a MOV from the inst->base_mrf and
sets the src0 appropriately. The indirect sampler case did not have a
call to gen6_resolve_implied_move().

The fs backend avoids this because the platforms that support dynamic
indexing of samplers (IVB+) have been converted to not use the
fake-MRF hack, and instead send from proper GRFs.

This patch makes it call gen6_resolve_implied_move before setting up
the indirect message. This is similar to what is done for constant
sampler numbers in brw_SAMPLE.

The Piglit tests for sampler array indexing didn't pick this up
because they were using a texture with a solid colour so it didn't
matter what texture coordinates were actually used. The tests have now
been changed to be more thorough in this commit:

http://cgit.freedesktop.org/piglit/commit/?id=4f9caf084eda7

With that patch the tests for gs and vs are currently failing on
Ivybridge, but this patch fixes them. There are no other changes to a
Piglit run on Ivybridge.

On Skylake the gs tests were failing even without the Piglit patch
because Skylake needs the source registers to work correctly in order
to send a message header to select SIMD4x2 mode.

nv50/ir: OP_JOIN is a flow instruction

OP_JOIN instructions are assumed to be flow instructions and mercilessly
casted to FlowInstruction.

This patch fixes an instance where an OP_JOIN is created as a plain
instruction. This can cause crashes in the ir printer.
